SITUATED AGENTS

John S Gero Agents – Situated Agents Basic Ideas Interaction not just encoding Construction not just recall Cognitive Science Dewey (1896): “Sequences of acts are composed such that subsequent experiences categorize and hence give meaning to what was experienced before.” Gero (1998): “where you are when you do what you do matters” Experimental Studies Schön and Wiggins (1992): “interaction of making and seeing” Suwa, Gero and Purcell (1999): “Sketches serve as a physical setting in which design thoughts are constructed on the fly in a situated way.” Situatedness
